6) In the figure shown, body A is connected to body B by a cord which goes through smooth rollers at C. Body A weighs 15 lb and body B weighs 12 lb. The coefficient of friction between body A and the horizontal surface is 0.6. At the instant shown the cord connecting body A to the wall is cut. What is the minimum velocity body B must have in order to cause body A to slide. What is the tension in the cord at this instant. 30° 3.0'
What is the smallest acceleration that bar A needs to move horizontally to maintain bodies 1 and 2 motionless with respect to the bar? The bodies' masses are the same, and there is k times as much friction between them and the bar. The pulley's mass and threads are insignificant, and there is no friction within. A 2
Learning Goal: In 1687, Isaac Newton presented three basic laws that describe the motion of a particle: • First law: A particle originally at rest, or moving in a straight line with a constant velocity, will remain in this state provided that the particle is not subjected to an unbalanced force. Second law: A particle acted upon by an unbalanced force, F experiences an acceleration, a, that has the same direction as the force and a magnitude that is directly proportional to the force.

Two bodies, A and B, weighing 50 kg and 25 kg, respectively, are connected to each other by a rope mounted on a pulley without friction. Five seconds after the body system is released from equilibrium, body B descends at a speed of 10 m / s. Calculate Body acceleration A (a), cable pull force S and coefficient of friction A across the ground (u).

The cart in figure 1 slides in the horizontal plane with an acceleration of 7 m / s². Body A has 7 kg of mass and there is no friction between the body and the support planes. Determine the horizontal force that the vertical wall exerts on the body, considering it in relation to the cart.
The mass of the m_1 block in the figure is 40 kg, and the mass of the m_2 block is 10 kg. There is no friction between the m_1 block and the ground. The friction coefficient between m_2 and m1 is 0.6 and the kinetic friction coefficient is 0.4. A horizontal force of F = 100 N started to pull the m_2 block as shown. In this case, calculate the accelerations of m_1 and m_2 blocks?
